std::optional< math::Vector3R > calcRefractDir (const math::Vector3R &I, const math::Vector3R &N) const
 Calculates the normalized refraction direction.
 
std::optional< real > calcRefractCos (const math::Vector3R &I, const math::Vector3R &N) const
 Calculates the cosine (signed) of refraction direction. This method is similar to calcRefractDir(), but is slightly more efficient as it returns the cosine of refraction direction only.

Detailed Description

Dielectric-dielectric interface Fresnel effect.

The formulae used are exact ones, i.e., no approximation is made.

Constructor & Destructor Documentation

◆ ExactDielectricFresnel()

ph::ExactDielectricFresnel::ExactDielectricFresnel ( real iorOuter,
real iorInner )

Member Function Documentation

◆ calcReflectance()

math::Spectrum ph::ExactDielectricFresnel::calcReflectance ( real cosThetaIncident) const
overridevirtual
Parameters
cosThetaIncidentCosine of the incident angle.
Returns
The reflectance of the interface on the specified angle.
Note
cosThetaIncident is signed, so inner and outer sides can be determined.

Implements ph::DielectricFresnel.
